As a followup to the mailing list. Updating the machine solved this issue. But the bugzilla still applies since it was blocking the upgrade. Thank you all. On 2 Aug 2021, at 13:22, Vinícius Ferrão via Users mailto:users@ovirt.org>> wrote: Hi Ales, Nir. Sorry for the delayed answer. I

Hi, As I see this is an issue hard to get help on, I'll ask it otherwise: Alternatively to backup and restore, is there a way to migrate an oVirt-manager installation to other machine? We're trying to move the manager machine since the current physical machine is getting short of resources,

I have asked our VM maintainer to run the command # virsh -r dumpxml vm-name_blah//as Super user But no output : No matching domains found that was the TTY output on that rhevm node when I executed the command. Then I tried to execute # virsh list // it doesn't list any VMs !!!

[ovirt-users] posix storage migration issue on 4.4 cluster

2021-08-03 Thread Sketch
I currently have two clusters up and running under one engine. An old cluster on 4.3, and a new cluster on 4.4. In addition to migrating from 4.3 to 4.4, we are also migrating from glusterfs to cephfs mounted as POSIX storage (not cinderlib, though we may make that conversion after moving to

When I did the VM this time, I did pre-allocate all of the space. The first time, I was just curious if Windows would even run ok under oVirt and it does appear it will. Next.. I need to get a couple Solaris VMs actually working. I've seen some 'hacks' out there that others have reported

Yes - local as in 5400 RPM SATA - standard desktop, slow storage.. :) It's still 'slow' being 5400 RPM SATA, but after setting the new VM to 'VirtIO-SCSI' and loading the driver, the performance is 'as expected'. I don't notice with with the Linux VMs because they don't do anything that

I believe "local" in this context is using the local ovirt Host OS disk as VM storage ie "local storage". The disk info mentioned "WDC WD40EZRZ-00G" = a single 4TB disk, at 5400RPM. OP the seek time on that disk will be high. How many VMs are running off it? Are you able to try other storage? If
